This footage of Fuji in Japan was recorded last year by motion detection cameras installed by Daichi Fuji, an astronomer and curator of a museum based near the famous mountain. The researcher was observing meteors, but recorded something completely different.

The mysterious green laser radiation turned out to be a NASA satellite. The ICESat-2 device produces 10 thousand pulses of laser radiation per second, measuring in detail the characteristics of glaciers, reservoirs, urban landscapes and even cloud cover. Usually these lasers are not visible, but with certain clouds they can be noticed.

The ICESat-2 team found Fuji's post on social networks and decided to check if it was really their satellite that was causing the green glow. Analyzing the data of the September night last year, satellite specialist Tony Martino from NASA managed to establish that at that moment there were two thin layers of clouds over Japan. This made the laser radiation of the device visible.
